Sudha Arunachalam is an Associate Professor of Communicative Sciences and Disorders at NYU. She holds a Ph.D. in Linguistics and M.A. in Psychology from the University of Pennsylvania, and a B.A. in Linguistics from the University of Southern California.
In her research program, she examines how infants, toddlers, and preschoolers acquire their native language. She studies children who are developing typically, children with autism spectrum disorder, and children with language delay. In collaborations with researchers all over the world, she has studied children who are acquiring languages other than English, including Turkish and Korean. She is particularly interested in the learning mechanisms underlying language acquisition and in how caregiver-child interactions support learning. This interdisciplinary work integrates insights from the fields of communication disorders, linguistics, and cognitive and developmental psychology, and it involves several behavioral methods with a focus on eye-tracking. Sudha has authored dozens of journal articles, and her work has been funded by the National Institutes of Health, the National Science Foundation, and several private foundations. Prior to joining NYU, Sudha was an Assistant and then Associate Professor at Boston University in Speech, Language & Hearing Sciences, and Linguistics.
